Example Embodiment

[0019] The specific implementation of the present invention is as follows:

[0020] This embodiment is a power amplifier source for magnetic resonance coupling wireless power transmission. The power amplifier source includes a radio frequency signal generation module, a radio frequency power amplifier module, a constant current module, and an overvoltage protection module; when the power amplifier source is connected to an external DC source, The radio frequency signal generation module generates a radio frequency signal of the required frequency, and the power amplifier module amplifies and outputs the radio frequency signal; the overvoltage protection module detects the voltage to be detected at the rear end of the power amplifier in real time, and when the voltage to be detected is higher than a preset When the reference voltage value is, the overvoltage protection circuit feeds back excess energy from the back end to the input DC source, so that the back end voltage of the power

Abstract

The invention discloses a power amplifier source for magnetic resonant coupling wireless power transmission. The power amplifier source comprises a power amplification module and a circuit feedback module; the power amplifier module adopts a planar circuit structure and an overall circuit with a power amplifier rear end to detect the energy feedback to perform the overvoltage protection, thereby realizing the radio frequency small signal input and large power signal output; the power amplifier source has excellent stability when the more than 70% of radio frequency power amplifier source efficiency is realized, the use field of the power amplifier source is broadened while the circuit module is simplified, and the stability of the wireless power transmission efficiency output is improved. The radio frequency power amplifier source of the invention is a planar structure, and can be processed through a printed circuit board so as to realize the power output. The power amplifier source is a small planar structure and suitable for various small power electric devices, and can provide the corresponding power input for the single-to-single and single-to-multiple wireless power transmission of the portable computers, tablet computers, LED lighting devices, loudspeaker boxes, mobile communication terminals and small consumer electronics.
